The main goal of this article was estimation of the lag time of direct runoff in Służew Creek catchment, located in Warsaw (Poland). To calculations there were used measured data of rainfall (Okęcie rain gauging station) and data of direct runoff at the Berensewicz Pond water gauge. The IUH based on the Nash model, in which catchment is shown as a cascade of N linear reservoirs with retention parameter...
Celem pracy było wyznaczenie czasu opóźnienia odpływu i parametrów modelu Nasha w zlewni Potoku Służewieckiego po profil Staw Berensewicza na podstawie danych opad-odpływ zarejestrowanych w zlewni. Analizę przeprowadzono na podstawie danych pomiarowych z półrocza letniego 2007 roku dla dwóch metod rozdziału opadu całkowitego, tj. dla metody CN-SCS oraz metody funkcji wykładniczej. Do analizy wybrano...
A cascade of N linear reservoirs, with retention parameter k of each of the reservoir, were accepted as conceptual model for transforming the effective rainfall into direct runoff. On the basis of four recorded rainfall-runoff events in a small agricultural catchment of the Gzówka river, an analysis of the influence of the method of effective rainfall estimation on lag time and Nash model parameters...
